Bolivia (Quechua: Buliwya; Aymara: Wuliwya; Guarani: Volívia), officially known as the Plurinational State of Bolivia (Spanish: Estado Plurinacional de Bolivia), is a landlocked country located in western-central South America. It is bordered to the north and east by Brazil, to the southeast by Paraguay, to the south by Argentina, to the southwest by Chile, and to the northwest by Peru. Although only one-third of the country is located in the Andean mountain range, its largest city and principal economic centers are in the Altiplano. More: en.wikipedia.org.
